You (like myself) might well be decended from Albert or Arent Bradt who came from Holland in the mid l600s and settled in upstate New York (near Albany, New York)
My ancestor was Albert Bradt. I've also been told that I have Mohawk blood, as well as Abernaki. In my case the Mohawk came if I remember correctly through the Vanderpoel.
I'm also an llth generation Waldron and the Bradt line is via Judah Bradt who married William Waldron in l804. I have quite a few old portraits at my website www.authorgloriawaldronhukle.com
. Hope some connect for you.
